1 '0 all whom it may concern:

Be it known that I, lVALTnn KRAUsn, a citizen of Germany, and residentof Friesuck, iii-ark, Germany, have invented certain new and usefulImprovements in Irrigation Hystei'ns (for which I have filedapplications in tlrerniany, August 13, 1917; Austria, January 2S),191$), Patent No. 85,055; Hungary, llebruury '1, 1919; France, February1.1, 1919, Patent No. 517,859; Spain, February 27. 11119, Patent No.(39,176; Denmark, February 1, 1919, Patent. No. 27,076; Belgium,February 21. 1919, Patent No. 279,058; Netherlands, March 10, 1919;Italy. February 25, 1919, Patent No. S T/5&2; Luxemburg, October 4,1919, Patent No. 11,525; Rouman-ia, October 7, 1919, Patent No. 5.038;,Sweden, January 3 1, 1919; Canada, May 26, 1920, Patent No. 220,938;Great Britain, January 27, 1920, Patent No. 1383-13; Poland, July 5,1920'; Czechoslovakia, June 18, 1920; Argentine Republic, August 3,1920), of which the following is a specification.

My invention relates to improvements in irrigation systems, and moreparticularly in irrigation systems of that class in which the water issupplied to sprinkling devices through conduits which consist of aplurality of sectional pipes carrying the sprinkling devices and adaptedto be connected by joints permitting of a ready assembling anddisconnecting of the pipes for carrying the same from one point of useto another one. Such pipe sections are ordinarily made as long aspossible in order to reduce the work connected with assembling theconduit, and for the same reason supporting members or legs areconnected therewith, an attendant being able to carry the sections andtheir supporting members in the point 01 use. in c nstructions now inuse it is dillicult or aln )sl impossible to place a pipe sec tion withits supporting members on the ground in the oper position for beingjointed to a tion which has before been rought into position without;shifting the same over the tield, which is objectionable because therebythe plants are injured. The object of the improvements is to provide a.construction whereby the sections can directly be placed on the groundin the proper position relatively to the other sections, so that muchtime is saved in assembling the conduits, and all the sections can beplaced in the proper positions whereupon all the Serial No. 383,020.

joints are made, which greatly reduces the amount of walking required ofthe attendant. ith this and other objects in view my ini'ention consistsin the matters to be described hereinafter and particularly pointed outin the appended claims. For the purpose of explaining the invention twoexamples embodying the same have been shown in the accompanying drawing,in which 1 and 2 are side views of the said examples, and Fig. 3 is anend View of the construct'ion shown in Fig. 1, partly in. sect-ion.

In Figs. 1 and 2 I have shown the ends of two pipes forming a part ofthe sprinkling conduit. But I wish it to be understood. that myinvention is not limited to the use in a sprinkling apparatus. As shownin Fig. 1 the sprinkling pipes 11 and is are supported on and rotatablein supporting members or legs 9 and m, and from the said legs bent armsand Z project upwards which are formed at their ends respectively with anotch n and a tooth 0 adapted for engagement with each other. lVhen thearm I is set on the arm 2' with the notch n and tooth 0 in engagementwith each other the pipes it and 7. are located the proper distanceapart, whereupon the joint 8 can be made, which as shown is in the formof a claw coupling. lVith a coupling of the character illustrated,rotation of one of the pipes in its supporting member, relatively to theother pipe, in the proper direction, will tend to open the joint by asort of cam action and thus facilitate separation of the pipes whendesired. Relative rotation of the pipes in the opposite direction willnot affect the tightness of the joint. However, if the ground on whichthe members 9 and m are supported is not lewd, and also in some caseswhen (lisconnertii'lg the j int, there arise ertain dillirulties whichare avoided in the conslrurlion shown in Fig.

In this cons uction e p equipped ith a support! g 1116111116.; f], whichlonger thai'i the supporting inein li-er HZ, ot the pipe li', so thatthe inei'nber 721, does not rest on the gri'iuniil when the arui 7,bears on the arm in order to hare the member m, rest on the ground. theincur her i, is recited away from the arm 1-, in the direction of; thearrow shown in Fig. 2 and about the notch 72, While being engaged by thetooth 0 of member 1,. For more easily rocking the member g, I prefer toprovide the same with a rounded foot portion Fig. 3 shows that the leg 9of Fig. 1 is forked, its two diverging members being located insubstantially the same transverse plane, so as to afford a firm footingand prevent the pipe line from falling to one side or the other. Thesame forked construction is preferably adopted for the legs 11?,(Fig. 1) or 9,, m, (Fig. 2), the illustration in Fig. 3 being thoughtsuflicient to make this clear.

By providing spacing members of'the constructions referred to theattendant is enabled to first carry all the sectional pipes into theirproper positions and thereafter to make all the joints while walkingfrom one to the other once. Thereby the length of the way to be traveledby the attendant is reduced.

From the foregoing description of the invention the method of assemblingthe conduits will readily be understood. Preferably the attendant firstcarries all the pipes h, 70, etc. with their legs g, m, etc. to thedesired place, and when setting a pipe on the ground he hangs the pipeis with. its arm Z, or Z on the arm 2', or 11, respectively,

- whereupon the pipe ends are in their proper positions. Therefore it isnot necessary to shift the same over the ground, which would injure theplants, and would also require the attendant to look after the joints.After all the pipes have been brought to their respective positions theattendant walks along the conduit andmakes the joints.

I claim:

1. In an irrigation system a conduit composed of sectional pipes, jointsfor said pipes, supporting members connected with each of said pipes, sothat each of them will have its individual support, andspacing ,membersconnected with the pipes and ing arms connected with the pipes andformed respectively with a notch and a tooth adapted for engagement witheach other when the pipe ends are in their proper rela tive positions.

3. In an irrigation system, a conduit composed of sectional pipes,joints for said pipes, supporting members of different heights connectedwith said pipes, and spacing members connected with the pipes andadapted for engagement with each other when the pipe ends are in theirproper relative positions.

4. In an irrigation system, a conduit composed of sectional pipesprovided with mating joints of cam formation to cause the pipes to moveapart when rotated relatively to each other in a certain direction,supporting members in which said pipes are mounted rotatably, andspacing members, in mutual engagement, connected with said pipes.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
